Obesity Surgery

The basis of most Obesity Surgery (also known as Bariatric Surgery) is to restrict the amount of food able to be eaten and for satiety (feeling full) to be reached only after a small amount of food is eaten. The Roux-en-Y gastric bypass also has an element of mal-absorption where the area of the gut absorbing nutrients and calories is reduced. There are also less commonly used operations, which incorporate a greater deal of mal-absorption, but these are not commonly recommended for most patients.

It is important to understand that surgery is part of a multi-disciplinary management of Obesity. We refer many patients to our metabolic physicians. It is also very important to follow dietary instructions given by your dietician. MGOS uses several dieticians . Your lifestyle, body image and occasionally food behaviour can also change and some people also need to see a psychologist to help with these changes.

Each type of surgery has different techniques, potential early and late complications, variable expected amounts of weight loss and different requirements for follow-up. All these considerations are discussed prior to a recommendation for surgery.

These operations are almost always performed using Keyhole Surgery. Please click on the following links for further explanations of each type of weight loss surgery.
